(a) The Columbus Zoo conducts a study to determine whether a household's income can be used to predict the amount of money the household will give to the zoo's annual fund drive. The response variable in this study is A. all households in Columbus. B. the Columbus Zoo. C. a household's income. D. the amount of money a household gives to the zoo's annual fund drive. E. None of the above. (b) A researcher wishes to determine whether the rate of water flow (in liters per second) over an experimental soil bed can be used to predict the amount of soil washed away (in kilograms). In this study, the explanatory variable is the A. rate of water flow. B. amount of eroded soil. C. depth of the soil bed. D. size of the soil bed. E. None of the above. (c) A researcher measures the correlation between two variables. This correlation tells us A. whether or not a scatterplot shows an interesting pattern. B. the strength of a straight line relation between two variables. C. whether a cause-and-effect relation exists between two variables. OD. whether there is a relation between two variables. E. None of the above.
